DYEING-MACHINE.

To all '1f/toni t may Concern:

Be it known that I, HOWARD M. DUDLEY, a citizenot the United States, and a resident of Philadelphia, iii the county of Philadelphia and State of Pennsylvania, have invented `certain new and useful Improvenients in DyeingMachines, of which t ie following is a specication.

My invention relates to a dyeing machine and refers particularly to a machine adapted for the dyeing of textile fibers compressed within a dyeing chamber, the dyeing being accomplished by the forced passage of the. dyeliquor through the fiber mass.

Among the objects of my invention 1s a dyeing machine pzirticularly suitable tor the dyeing of warps in they ball, whereby the condition of the liber may be accurately and readily judged at any stage ot' the treatment without opening the dyeing chamber and whereby even results may he obtained with ont disturbing the -fber to be dyed.

Another object 'of my invention is a dyeingr machine in which the dyed goods may be after-treated with water, steam. nii"` or other materials or substances without handling the dyed goods, and whereby a series of batches of fiber may be treated simultaneously.

Other objects of my invention will be evident upon a considerationof my speeification and claims.

vI have found that. the even or uneven dyeing results obtained in a machine of this general character depend largely upon the particular shape of the openings` through which the dyeliquor enters theliber mass,

and that unevenness can be prevented by the use of .openings of a particular shape, the conformation of which enables the liquor to jspread itselffthrough the liber mass'without' the formation of channels of flow.

I have further found that this desirable result may berenhanced by inclosing the liber in a series of containers'and passing the treatinglqui'd through these containers and the fiber contained therein, first in one direction and then in the reverse direction.

V Infthe use of many dyest'ull's it is necessary, after dyeing to treat the dyedrgoods with, water for washing pnrposes,or with solutions of chemicals such as metallic salts f o'rfoxidizing products, for the purpose of after-treatment, or with oxygen or air for oxidizing or drying. purposes. In the fol-- lowing of these. after-treatments it is essen-` Specication of Letters Patent.

Application led March 13, 1917.

Serial No. 154,575.

tialthat every portion of the dyed goods be thoroughly and uniformly treated andthat the operation be performed as readily and quickly as ossible. All of these results are obtainable y the use of the device of my inventioin'in which thelgoods are placed in the dyeing chamber and then' rapidly, easily and completely dyed and after-treated without further handling of the goods and without the formation 'of channels by the liquids einployed. and uniform results with a minimum of time, labor and expense.

One form of my device is shown in the. accompanying drawings in which similar parts are designated by similar numerals.

are situated in planes parallel to and per- 5 pendicular to each other, their bases meeting at the angles, thus forming a series of rectangular openings 82, 82, the members 53, 53 ext. .iding upwardly and downwardly therefrom,

The operation of the device is as follows, assuming that the dyeing or treating operation has been finished, and thc device in the position shown in Figs. 1 and 2: The valves i 7.7, 75, 79, 89, 87, 77^, T5^, 79", 89^ and 8,7A are closed. The valve 84 is opened, al-

lowing all the liquid contained within the= receptacle to drain out. The pipe 35 is then uncoupled. The series of screw-bolts 70, 70, 70^, 70^ are withdrawn and the two trucks 56, 56AV are withdrawn slightly upon the tracks 58, 58, 8^, 58A from contact with the receptacle 23 by means of. the lever-arms 59, 59A, the latter corresponding to 59. Truck is then withdrawn from its position bef tween the trucks 56, o6^ by rolling it upon the tracks 22, 22. The receptacle 23 is then given a vquarter revolution by turning the wheel 29, and if necessary may be maintained in, 'that position hy the screw-bolt 94, the receptacle 23 then being in the position ,shown in Fig. 3. The series of screwbolts 69, 69 (Figs. 1 and 2) are then withdrawn from engagement with the lugs 32, 32 and the member 67 withdrawn from within the receptacle 23. The fiber-holding members` 46, 45, the member 83 andthe liber-holding member 44 is then remcred in the order Stated by means of hooks inserted beneath the pins 100, 100, in the lugs 49, 49, as illustrated in Fig, 3. When it is desired to load the device with `fiber, fiber is introduced into the fiber-holding tray 47, the device bein in the position shown in Fig. 3. 'Thefiierlioldlng member 44 with the fiber is'thcn similarly placed upon the member 47. The member 83 is then introduced, no iberbcing i contained therein, and finally the fiber-hold'- ing'member 45 and 46 with fiber are intro-V duced. 'The member 67 is then introduced,

its lugs 68, 68 abutting upon the lugs 49, 49

. of the member 46, and thc series of fiber-holdi ing 'members brought' intointimate andV fixed ,contact with each other by means of the screw-bolts 69, 69. The receptacle 23 and its contents `'are then given a quarter revolution by means of the wheel 29 and its con'- necting members.V The truck 20 Vwith the re eep 3l is. then d. along the tracks y l fr. `ta `efspositioued'hee .1."

' Tand 2. The trucks 56,'56^ with the members attached` theretoV are thenI moved inwerdly along the tracks 58, '58^ until the flangemembers 66, 66A of lthe members 64,

`64'*` abut against themennieis 6i' and i5 hev tween which a gasket has been placed, and the joints made tight by means of the series of screw-bolts 70, 7()^` The pipe 35 is fixedly attached to the shelll. The device is then in the position shown in Figs. 1 and 2.

The dyeing operation is then conducted as follows All oi the valves with the exception of valves 7 9^, U1^ and 93 are closed. The pump 7l.A is then started, which takes thc dye liquor from the dissolving tank not shown to which pipe 78^ is attached, through the pipe 78,^, and forces itthrough the various filmr-holding `t rays 47, 44, 83, 45 and 46 into the pipe 92 through which it flows into the reserve tank 38.' W hen allV of the liquor from the dissolving tank has been delivered to the pump 71A, the valve 79^ is closed and the valve 77^ is opened, thus allowing a free 4-ireulation of liquor by means of the pump 7l^ from the tank 38, through the device and the fiber contained therein back into. the tank 38. lf it is desired to reverse the flow of the d ve liquid through the device and the iiber, the pump 7lA is stopped, all of the valves with the exception of valves 77, 91 and 93A are closed and pump 71 started, thus allowing a circulation of the liquor in tank 38, through the pipe 7G, the pump 71, the devices and through ythe pipe 93^ back into the tank 38. If itis desired to pass the liquid from both ends -of thel device towardithe middle. and out through the space formed by the member 83, all of the valves are closed with the exception of 77, 91, 77, 91^ and 37 and both pumps 71 and 71A started, the liquor will thus circulate from the tank 38, through both pump 7l and 71^ inwardly through the iberand back into thetank 38 through the pipeell' When thc dyeing operation is completed` the liquor in the dyeing chamber lis removed hy allowing it to drain throughthe pipe,1 08 by opening the valve 84 at the bottom thereof. f

li it is desired to wash the goods, water admitted through the pipe74, 741 by opening the valves 75 and 75^, and the Water forced through the device and the goods contained therein, the other valves beirigin such` an open or closed position as to cause the water` to enter'eithcr through the pipo 74 or74^ and exit;` through the other one, the circulation heilig caused by either.the pump 71.01' 71'^.

Ii` itis desired to treat the dyed fiber with air, the valves 87 and 89'* are opened andy -V the exhaus he and fiber, by the suction upon the pipe 88,-A -or by using the compression side-of the pump not shown) air may be forced .through the device und the fiber in au opposite direction'l from that just descrilied.
